SUBSTITUTE FOB PRINTERS BRASS RULES.

Application filed september 9, 1910. Serial No. 581,325.

To all whom it may concern Be it known that I, Asnron G. STEVEN- son, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Substitutes for Printers Brass Rules, of which the following is a full, true, clear, and exact description.

My invention relates to improvements in printing devices and has particular reference to printers rules for printing or impressing lines upon printable surfaces.

The object of the invention is to provide a cheap and satisfactory substitute for the printers brass rule s usually employed by printers for printing lines.

M 4 or object of the invention is to provide a'rule'for printers use which,-while sired style or kind of ,line or border.

The rules usually employed in composing printing forms are type high bars or strips of brass havingone edge formed for printing or impressing a line, and as this material is comparatively expensive and the bar of necessity has to be accurately formed, it is seen that the capital which is tied up in this adjunct to a printing office may, and frequently does, run into quite large amounts. It is with the object of reducing the necessity of this large investment and of producing a rule which will be as cgnvenient and satisfactory to use as the brass rule now employed, that I have produced the rule which is the subject of this application. Y My invention consists in a composlte rule having its main body portion formed of a comparatively inexpensive mater1al and its upper or printing edge or portion formed of a comparatively hard wire, strip or rod suitably secured to the body portion.

'Ihe invention further consists in a rule having its major body portion formed of paratively hard metal printing member se-,

cured upon the uppersurface of the body portion by means of said flanges or lugs, the

combined height of the body portion and the printing member being substantially body member of comparatively large cross sectlonal area, the combined height of the two members being substantiall t e height. y 'yP My invention will be more readily under- I stood by reference to the accompanying drawingsforming' part of this specification and in which Figure l'is an enlarged perspective view of a rule for printers use, embodying myinvention; Flg. 2 1s a cross section of the rule shown in Fig. 1 but on a still larger scale; Fig. 3 is an enlarged perspective view of a composed body of type illustrating the use or application of my novel rule; Figs. 4 and ,5 are cross sections of rules showing slight mlodifications of the. hard metal printlIlg.,IIlQIiI)lZbI'; Fig. 6 is a section similar to ut showing a modified form of the hard nietal ruling member; Figs. 7 to 18 inclusive are similar sections of rules illustrating still further modifications of the hard metal ruling member; Figs. 19 to 22 inclusive are sections similar to Fig. 2- but illustrating the mounting of various forms of the hard metal ruling member upon the soft. metal body portion; Fig. 23 is an enlarged side elevation of a rule or leader designed to print dots; Fig. 24. is a vertical cross section of the rule on the line 24-24 of Fig. 23; Fig. 25 is an enlarged side elevation of a rule or leaderformed to print dashes; Fig. 26 is a vertical section of same on the line 26-26 of Fig. 25; andFig. 27 illustrates a very broad ruling member and its mounting- In said drawings A represents the rule as a whole which is built up or composed of two parts, the main body portion B and the printing member C. As clearly illustrated.

ing devices. i The rule, as a whole, serves as a substitute for the usual-brass rule'used for a similar purpose and can he formed. to print or impress all of the lines, marks or 7 other impressions for which such-devices are and size (of the commonly employed, the bod B of the rule "being made of a thickness-an its upper surface of a shape to correspond with the shape printing member C used therewith. In ot er words, the particular shape of the upper surface of the body portion is not an essential feature of the inven- 'tion, except to the extent that it is formed to correspond with the shape of the ruling member used therewith to the end that the ruling member may be and is rigidly or securely'held in place upon the body portion. In the preferred form of rule, as illustrated in Figs. 1, 2 and 3, and which is adapted tov be associated with.printing devices of ordinary or usual height the body ortion B, which is preferably of sin elght and is made of type metal is provide upon its upper surface or edge, with .thin feather edge flanges, lugs or ribs D extending longitudinally thereon and spaced apart to receive the base E of the ruling member G between'them. The rulingjn'ember G is preferably made of brassor some equally are greatly enlarged from the actual sizes as hard metal and :,s trian lar. incross section, presenting a flatub'ase Eto the top or supporting edge G of the body portion, and haul-1g a printing ,s'urfa'ce H on its upper edge; The ruling member C, is held rigidly in place upon the body portion by the ribs or flanges D which are bent, formed or compressed downwardly upon the side faces J thereof. e

' It will be noted that all of the drawings the printing member C is comparatively so smallin cross section that its features would The preferred form of ruling edge or member C is an equilateral triangle in cross sequently lighter in weight than the preferred form while still preservingthe same width of base. Fig. 7 is an enlarged section of the preferred form of ruling member distinctly showing the three equal ruling edges or surfaces. The form of ruling member shown in Fig. 8 is similar to the preferred form except that each of its edges is a different width than the other two, thereby producing a member by means of which lines of diifering widths can be printed depending upon which edge is arranged uppermost. Fig. 9 illustrates the form of ruling member shown in Fig. 6 but greatly en.- larged, in order to clearly illustrate the concave side faces and the three equal ruling surfaces or edges. The modifications of the ruling member illustrated in Figs. 10 to.18 inclusive are sufficiently self eiplanatory not to require any further explanation. Those show-n in Figs. 20am]; 21 illustrate still other modifications of the invention, the 'rulingmember C being rovided' with parallel side' faces K and have longitudinal bent over ends of the flanges D. In the form' illustrated in Fig. 22 the ruling member is prorided with a single dovetail groove M in its under side and the body portion B is provided with a single central longitudinal rib N to correspond therewith. In securing the ruling member upon the body portion in this instance the rib N is compressed or deformed to fill the dovetail groove M and engage the inclinedwalls thereof. The rule illustrated in Fig. 27 is particularly adapted for printing a very wide or heavy line or it may be provided upon its broad printing surface with border lines or scrollwork of any desired character. The rules illustrated in Figs. 23 to 26 inclusive are formed to print dots and dashes; and may be formed slightly higher than type height to impress vweakened lines in the material being printed.

The body portion B which forms the major portion of the rule serves as a support as well as a reinforcement of the com.

paratively slight ruling member C. While this body portion is preferably made of type .metal, which is a comparatively inexpensive material, it might, under some circumstances base of which is narrower than the otheiy be advantageous to make it ofother inexsides, and which is consequently of less cross sectional area and weight than the preferred form. The form of ruling member illustrated in Fig. 5 is particularly adapted for use inclose work as the printing edge is disposed adjacent one edge of the width of the rule in position to print a line very close to The form illus- I trated in FigQfi is particularly advantageous 'asthe lfa'ce's of the ruling, member are concave instead of flat and the member is conpensire material, the broad idea. of my invention being. covered by a rule, the major portion of which is composed of an inexpensive material and having a ruhng edge of suitably hard material secured thereto.

From the foregoing it will be seen that my novel rule is a comparatively cheap substitute for the ordinary or usua brass rule and that it is capable of being formed to accomplish ,all 0 the purposes or which the ordinary rule may be used.
